Grocery store aisles are stocked with products that promise to kill bacteria. People snap up those items to protect themselves from the germs that make them sick. However, new research from Washington University in St. Louis finds that...

How wildlife respond to climate change is likely to be complex. To better understand the effects of climate change on the bird community in the Sierra Nevada region, new research published today from Point Blue Conservation Science examines...

Climate change has fueled coral reef bleaching throughout the tropics, with negative consequences for reef ecosystems and the people who depend on them. A new study finds that in the Caribbean, independent island nations such as Cuba and...

An insect's gut might seem an inhospitable place to settle in, but diverse microbes nonetheless make their home there. Yet in the gut, there's a struggle for the nutrients needed to survive among the resident bacteria and fungi...

Based on new data published today in the journal Science, it seems increasingly likely that an asteroid or comet impact 66 million years ago reignited massive volcanic eruptions in India, half a world away from the impact site...

Bacteria in the gut do far more than help digest food in the stomachs of their hosts, they can also tell the genes in their mammalian hosts what to do.
A study published today in Cell describes a form...

LSU Mechanical Engineering graduate student Tatiana Mello of Piracicaba, Brazil, is currently working on genetically engineering and optimizing E. coli bacteria to produce bioproducts, like biodiesel, in a cost-effective manner. This undertaking has garnered the attention of many...

The smell of food induces a variety of physiological processes in our body. Thus, the production of saliva and digestive enzymes is stimulated before the actual food intake in order to prepare the gastrointestinal tract for the upcoming...
